ProBoard v2.15 used version 4.12f of this program. I am waiting for information from the author to see if v2.16 used version control since it is not reported in the PB manual anymore.
 

The technique works by embedding CRC or checksum values into the executable file. When the user program is started, it checks itself against the CRC values embedded when the file was first compiled to see if any changes have been made.

The program is a faster revision of the version published in PC Magazine, Aug 1989 (and includes a correction for a bug in that version).

These programs have been compiled under Turbo C 2.0 and MSC 5.1. They have not been tested with other compilers.
 

JPTUI provides many features which allow you to quickly create professional, quality user interfaces for MS-DOS programs, including windows, menus, buttons, edit boxes, tab-bars, and much more.

This library supports English, French and German.

Don't forget to read the technical information to avoid compiling problems ***** Note Technical Information *****.
 

What is the advantage? The difference file is smaller and more suitable for distribution of updates, especially by modem or via Internet.

As an example, imagine you've just discovered a terrible bug in your few-megabytes-application last release. Now you have to redistribute to hundreds (thousands?) users a bug free release, spending a lot of time in copying disks. By MDIFF you could generate a small file containing only the bug fixing and distributing it (maybe via email) you could save time and money!

Included in MDIFF packet you will find a set of freeware C libraries (for Microsoft, Borland and IBM C/C++ compilers) to build your own patch appliers programs, so you can freely include the patcher in your own applications!
 

RegKey is compatible with a wide variety of programming languages and operating systems. Specific instructions for using RegKey with C compilers from Microsoft, Borland and Mix Software (for both DOS and Windows applications when supported by the compiler), Microsoft QuickBASIC, Microsoft Visual Basic for Windows, and Borland Turbo Pascal (both DOS and Windows versions) are provided.

Suppoprted versions are:

Few programmers have the time and resources to obtain appropriate codes for every printer. Fortunately, you don't have to. The Printer contains printer codes for over 700 printers in the registered version and over 50 in the shareware version.

Additional functions are made available after registering.
 

It can identify:

Version numbers were added for past and present Turbo-C compilers. WHATIS can identify a *limited* number of assembly programs (usually multi-module programs assembled with TASM).

WHATIS identifies any program that has been compressed with Bellard's LZEXE.exe program.

Due to the age of this program, not all files, especially the more modern ones, may display invalid information. The only way of knowing, is to try it out on the file first, then use common sense for the rest!
